Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

Community guidelines

Do not use URL shortening services: always submit the real link.

Begging/asking for bitcoins is absolutely not allowed, no matter how badly you need the bitcoins. Only requests for donations to large, recognized charities are allowed, and only if there is good reason to believe that the person accepting bitcoins on behalf of the charity is trustworthy.

News articles that do not contain the word "Bitcoin" are usually off-topic. This subreddit is not about general financial news.

Submissions that are mostly about some other cryptocurrency belong elsewhere. For example, /r/CryptoCurrency is a good place to discuss all cryptocurrencies.

Promotion of client software which attempts to alter the Bitcoin protocol without overwhelming consensus is not permitted.

No referral links in submissions.

No compilations of free Bitcoin sites.

Trades should usually not be advertised here. For example, submissions like "Buying 100 BTC" or "Selling my computer for bitcoins" do not belong here. /r/Bitcoin is primarily for news and discussion.

Please avoid repetition — /r/bitcoin is a subreddit devoted to new information and discussion about Bitcoin and its ecosystem. New merchants are welcome to announce their services for Bitcoin, but after those have been announced they are no longer news and should not be re-posted. Aside from new merchant announcements, those interested in advertising to our audience should consider Reddit's self-serve advertising system.

Download Bitcoin Core

Bitcoin Core is the backbone of the Bitcoin network. Almost all Bitcoin wallets rely on Bitcoin Core in one way or another. If you have a fairly powerful computer that is almost always online, you can help the network by running Bitcoin Core. You can also use Bitcoin Core as a very secure Bitcoin wallet.

We previously collected donations to fund Bitcoin advertising efforts, but we no longer accept donations. The funds already donated will be spent on some sort of advertising, as intended. As of now, 10.35799117 BTC was spent out of 22.51357574. If you have ideas for the remaining BTC, see here for more info.

I am thinking about designating an old core2duo dell tower of mine to be for offline/cold storage/air gapping my bitcoin.

Does anyone have an optimized setup for what I’m talking about? Or any suggestions from similar experience? I would be using existing hardware so the investment would be minimal.

The only cost would be a kvm switch which I don’t yet have. A kvm switch would make the experience of switching between 2 towers & perhaps a laptop/docked laptop much easier.

I’m also wondering about things on the software side- would I be using a USB stick and a copy of electrum on the cold storage tower and the internet-connected tower?

TLDR I have a stack of crap https://i.imgur.com/1SpB4sl.jpg that I want to put to use. I think that using this old hardware to air gap my wallet would be neat. Looking for advice on hardware+software suggestions.

These are I believe all core2duos. Not sure about ram but there’s 1 tb of storage on one of them. (Perhaps that can function to be my own server?)
